Title: Compressible printing blanket and method of manufacture
IPC: B41N10/04
Filed: 1973-02-16
Abstract: 1416253 Laminated printing blanket DAYCO CORP 16 Feb 1973 [24 Feb 1972] 7814/73 Heading B5N [Also in Divisions B2 and B6] A printing blanket comprises at least one fabric base ply, a surface layer and a compressible intermediate layer 15 of elastomeric material having a closed cell structure 19 of unconnected, uniformly distributed voids, each void containing compressible particles. In a method of making the blanket cured latex foam rubber is ground into particulate form, the particles are incorporated into an elastomeric matrix and spread on to a fabric base, an elastomeric surface layer is formed on the matrix and the whole assembly is cured. In examples, 15 or 25 parts of particles of average size 153 Á were mixed with 100 parts toluene and 100 parts butadiene-acrylonitrile rubber, with zinc oxide, carbon black and an accelerator. The mixture was spread on a farbic and heated to 100 F. to remove most of the solvent. A fabric layer, was then placed on the mixture, coated with acrylonitrile-butadiene rubber and the assembly cured at 290 F.

Title: Improvements in and relating to closures for collapsible tubes or containers
IPC: B65D39/08
Filed: 1924-03-27
Abstract: 214,598. Brustlein, J. April 17, 1923, [Convention date]. Plug stoppers, screw; stoppers fitted with spatulas; screw stoppers formed to aid withdrawal; packing-rings for stoppers; sealing devices for.-A plug stopper for collapsable tubes comprises a screw 1, Fig. 1, a stem 5 extending therefrom and serving for imparting rapid rotation to the screw, and a collar 4 of considerably greater diameter than the screw and located between the screw and the stem, which collar serves for imparting slow forcible rotation to the screw and keeps it from contacting with any surface on which the stopper may be laid. As shown in Fig. 1, the stopper is formed in one piece, the collar being formed by turning or pressing, and a shoulder 6 makes a tight joint with the top of the collapsable tube 3. The stopper shown in Fig. 3 comprises a single piece of rod bent to form a collar 4. In modifications, the collar is formed separately and is secured between two enlargements of the stem which may be hollow. In other forms, a bowl-shaped collar is secured to a sleeve on the stem, or the collar comprises a disc out of which are punched radial tongues adapted to be bent up and secured to the stem, the unaltered portion of the disc being also secured to the stem. The stopper may be formed in three pieces. The screw 1 shown in Fig. 18 and the stem 5 present opposed heads 17, 18 which are secured together by the inturned edges 21 of the collar 4, or by a ring 26, Fig. 25, which constitutes the collar, projections 20 on the collar or a loose key 27 preventing the screw and stem from rotating relatively to one another. In another form, the parts are secured together by electric welding. When the stem 5, Fig. 29, is hollow, the screw 1 is clamped within it by enlargements 29 formed on the stem on each side of the collar 4. In all these forms a shoulder below the collar forms a tight joint with the top of the tube, but it may be replaced by a packing washer. A cork washer 33, Fig. 32, is secured by a flange 32 on the collar 4. Alternatively, a sleeve 35, Fig. 44, adapted to retain the washer 33 is secured by an inturned flange 41 on the collar or by down-turned tongues punched out of the material of the collar. The ring 26, Fig. 25. may be adapted to secure the washer as well as the parts of the stopper. The stem may end in a double bevel, gimlet point, spatula, or other shape. In some cases, the collar is made domeshaped to cover the end of the tube, and may be perforated to receive a sealing wire. The screw may be conical and be applied to a liner in the tube. The mouthpieces of tubes specially adapted for use with the invention are made either conical or of a truncated cone shape intersected by two flats 51, Fig. 57, or as a truncated cone 50, Fig. 64, provided with flats 51 and having its axis arranged at an angle to the axis of the tube.

Abstract: 1,246,174. Voltage amplitude and frequency detectors; keying oscillators. WESTING- HOUSE AIR BRAKE CO. 14 Feb., 1969 [20 Feb., 1968], No. 8043/69. Headings H3A, H3R and H3T. [Also in Division G1]  In a signal amplitude detector circuit the signal is applied at 3, 4 as the power supply to an oscillator, the oscillator being shunted by a Zener diode Z1 so that above the Zener breakdown voltage the diode completes an A.C. path and permits the circuit to oscillate. The oscillator may alternatively be of RC, LC or RL phase-shift type (Fig. 2, not shown) or of Hurtley or Clapp configuration, The invention is described as applied to a failsafe vehicle speed control system in which if the speed as represented by the frequency of an A.C. signal from a tacho-generator exceeds the maximum permissible in the area a warning is given or the brakes applied. The A.C. signal is limited in amplitude and passed to one of a number of low pass filters selected in accordance with the maximum allowable speed or to an adjustable filter correspondingly set. The filter output is rectified and applied as the signal input to the amplitude detector circuit described above. If the speed and thus the frequency is above the limit the rectified output from the filter is insufficient to allow the circuit to oscillate and the absence of this signal is used to operate the brakes or the warning device.

[Class 136 (ii)] In a free-wheel hub with an internal backpedalling brake, the axially displaceable cone by which the friction brake sleeve is expanded is provided with teeth which engage teeth on an axially yieldable but non-rotatable member when the cone is displaced to apply the brake thus locking the cone against rotation. The brake sleeve 16 is supported at its ends upon a fixed cone 19 and on a cone 12 which is displaced axially to expand the sleeve against the hub 21 by co-acting helical cams or teeth 11, 10 formed on the cone and on the cage 9 of the driving ratchet rollers 8, when the hub driving member 7 is reversely turned by back-pedalling. The cone 12 has ratchet teeth 22 which during driving are disengaged from teeth on a non-rotatable but axially yieldable disc 24 so that the cone 12 is then' free to rotate with the member 7 but initial axial movement of the cone on backpedalling engages the teeth thus preventing backward rotation of the cone. The disc 24 is formed on a sleeve which is secured to an inner sleeve 25, the sleeves being prevented from rotation by engagement of parts 28 thereof in a slot 19<a> in the cone 19 and being permitted to slide axially against the action of a spring 27. A resilient ring 29 checks rotation of the cone 12 before engagement of the teeth.

As shown in Figure 3, the servo-valve 15 has an electric torque motor 25 energised by alternating current impulses which rapidly oscillate a pilot valve member which in turn feeds alternating hydraulic pressure impulses to a main valve member. The main valve member has a pair of outlet passages 32, 33 which are directed to the spaces at the opposite faces of piston 12. The piston 12 is mounted on a shaft 13 axially slidable in bearing sleeves 26 in cylindrical housing 11. Weights 14 are disposed upon reduced end formations of shaft 13 and are retained by nuts 28. The shaft 13 has a central 'bore 35 entraining leakage fluid which passes axially outwardly between shaft 13 and sleeves 26 and then passes to bore 35 by transverse passages 37. In a modification (Figure 2, not shown), a single central weight is supported on shafts which bear in the cylindrical housing and the servo-valve has its output pressure passages connected with the opposite ends of the housing whereby the shafts serve as pistons for vibrating the weight in accordance with operation of the servo-valve.
